1. Anyone wanna fix my sustainer circuit board trim pot that I snapped being a dickhead?
2. On the higher strings of sxc jazz, below the 5th fret the notes seem to check out at the 5th, even if I'm fretting the 1st. Is it just a case of some truss rod adjustment? Frets look reasonably level/not popping out

up to, mainly on the high e, but yeah. It's most prominent at the first fret although it's definitely still choking up till the 5th

truss rod probably needs a slight loosening. Hard to say how much, but try fretting the low and high E strings on the 1st and 15th fret, and loosen until there is a tiny gap between the top of the 8th fret and the bottom of the string. You can use capo for this too. Really small though, that you can just about stick a business card between
